Introductory Algebra

Descripción

Introductory Algebra is a primer for students considering an entrance level college algebra course. The textbook should not be considered a comprehensive treatment of algebra. The goal of the textbook is to teach a set of problem solving skills in some of the more fundamental areas of algebra.

The author uses a step-by-step problem solving technique that is demonstrated in an exacting format. These formats can often take an entire page to demonstrate the solution to a problem. Additional examples of problems are worked out completely using the exact problem solving format originally demonstrated.
